MACHINE FOR INSERTING FASTENINGS.

Specification of Letters Patent.

Patented Feb. 18, 1913.

Application led September 1 2, 1908. Serial No. 452.755.

To N tlf/10m it muy concern Be it known that I, 'Loris A. Ciseaux, a citizen of the United States. residingr at Beverly. in the county of Essex and Commonwealth of Massachusetts. have invented certain Improvements` in Machines for Insert-4 shapes andkinds, either for unitingl pei-manently or temporarily parts of the boots oi' shoes. or for purposes of ornamentation or resisting wear, the invention compreheiids. nevertheless. principles of construction and operation applicable to fastening inserting machines in general. whether such machines deal with previously formed fastenings. or make and insert. or insert and make. their own fastenings.

The various articles above included under the term fastening have in thc arts various designations according to che particular purposes which they subserve. F or the sake of brevity. however. thc tei-m fastening will be lused hereinafter to include everything of a nature. to he handled by machines of this kind.

A generalobject of the invention isto provide a fastening inserting machine which will operate effectively at speeds much in excess of those attained by such machines in use up to the present' time. Not only. however, does the invention aim to provide a fastening .inserting machine which will operate effectively nnder favorable conditions as to work and operator at speeds much in excess of those attained by such machines in use up to the present time,.but it aims furthermore to provide a machine which can be operated successfully under-ordinary conditions and by the average operator up to approximately its highest speed capacity, and yet which will have reserve capacity sutlicient to meet ,the demands upon it of the fastest and most skilled operator. l

To this end the invention aims to provide a machinejn which the various operations are performed with certainty and precision and in such succession or interrelation that the average time devoted to the insertion of a single fastening shall be reduced to a minimuni.

The invention aims further to provide a machine which, to the highest degree consistent with the variety of the demands made upon it, with the nature of the Worknpon which it operates and with the nature of thei operations performed upon said work, is automatic.

Although. in the illustrated embodiment of the invention. the number of operations of the inserting mechanism essential to the complete insertion of a single fastening 4has been increased. it will be seen that theseoperations have been highly specialized and ltherefore the time necessary to their separate performance has been inncli reduced,` and that such specialization has been so extended that tlie operations which, performed successively at a single fastening location, are essential to the complete insertion lof a fastening at said location, may be performed simultaneously at a plurality of successive fastening locations, and preferably are so performed when a plurality of fastenings are to be inserted in succession. 'It should not be implied from the use of the term specialize that in general the functions of single elements of former constructions have been broken up into steps to be performed by a plurality of elements of'the construction of this invention, for, in most cases, the reverse of this lproposition is true and not only docs a single element of the present construction perform the equivalent of the. functions of a plurality of elements of former constructions. but the operations vsimplification of the operations of forming and inserting fastenings has come simplifcation of the construction of the means which perform such operations, a reduction in the aggregate amount of movement of the parts of said means and also a reduction in the amount of power required to produce such A movement.

Another' object of the invention is to provide, in a fastening inserting ,machine in which the fastenings are formed bv sevrfastening. Preferably the said meansl forms ing, successively, portions from the'eiid of a continuous strip of fastening material, mechanism for gripping the strip', forcing the end into the work and severing the strip to forni a separate fastening and means for controlling positively the action ofthe said mechanism. Preferably a single means both grips the strip for inserting its end and vsevers the strip after the endA has been inserted. It is therefore desirable not only that the gripping action be limited to prevent severing atthev time 'the strip is gripped .ofthe sides of the portion intended to form the fastening, and shortening of the fastening, owing to the resistance .of the work to the insertion of the end of the strip. It is preferable that the severing operation -be positively effected. Preferably also `the means for controlling the .action of the gripping and severing means during the in"- serting operatioii'-contro1s said means positively at all times, thereby serving -to actuate said meansl to' grip the strip, to hold ,saidmeans in gripping relation to the strip,

to-actuate said'means to sever the stiip, and preferably to effect positively a releasing action of said means whereby a relative movenient of the strip and said means'. is permitted. i

Another object of the invention is the provision, in coinbinatioifiwith inserting iiiecha'nisni of the type of that hereinabove described, of means for forming a fastening receiving opening in the work to receive a the fastening receiving opening ata point upon 'the'work1l spaced from the point beneath the inserting mechanism a distance equal to the 'desired distance between succesl' 'sive fastenings in the fastening row and is 4preferably arranged to 'be-operated simultaneously with the .inserting mechanism.

Prior to this invention it has never been 'attempted, so far as known, vto combine meansA for forming an. opening to receive a fastening with a fastening inserting mechanism comprising a single means for both feeding and driving or for both driving and sever- A.ce

ing a fastening. Tliiscombination is an extremely important feature f the invention.

A convenient construction embodyingl the feature of the invention just referred to is onein "which the means"for forming the fastening'receiving opening -in the Work is operated in forming said opening by the means for inserting fasteniiigs, preferably latter. In its illustrated embodiment, this feature of the invention comprises an awl arranged to be driven into the Work by the gripping and severing mechanism hereinabove referred to upon its fastening insert.- ing movement, and a further feature of the invention is the provision of means operated by the inserting mechanism for foriiiiiig'a fastening receiving opening in the work which can be brought into and out. of operative 'relation to said inserting mechanism without interrupting the operation of said mechanism.

Another object of the invention is to pro-v vide, in a fastening inserting machine in which there are a plurality of sources of fastening supplyand means for forming in the work fastening means for inserting automatically in pre eterinined order inthe fastening receiving openings formed by said first-named. means .fastenings from said sources of supply.

Preferably the operation of the last-'named means. can readily be so varied thatl 'the order of the fastenings Vmay also be varied. Preferably also the means for forming the fastening receiving openings in the work is combined with means for inserting in. predetermined oriler from aplurality of.

sources of supply fasteiiings in a plurality 'of' rows formed by feeding the work between successive -fastening linserting operations. y

Another important fea-ture'.of the invenreceiving openinws,

lin the fastening inserting movement ofthe tion isthe provision, in a machine in which a fastening is partially-inserted into apreviously formed opening at one operation and is completely inserted at a succeeding operation, of means for forming the fastening t vreceiving opening, .means for partially 1nserting the fastening linto said opening,a'nd means for completing the insertion of .said fastening, all of which are 4arranged to operate simultaneously at three respective fastening locations upon the work.

A further important feature of the invention is the provision of three means having the functions of those' last described which are so. constructed and arranged that two of them may be operated from the third and that therefore power need be applied to only one of them.

Although, as liereinbefore suggested, in

ing in the preferred forni. of the invention three movements of the-inserting mechanism in the fastening inserting` direction are reqiiiredfitv will be notedpfrom the foregoing description of the operation of theI sep,-

arate means for performingthe' respective' steps in the insertion of a :fastening:that

when the machine-is operating Ato drive'sev- .the operation of inserting a'sing'le fastenoperative movement.

eral fastenings in succession,the insertion of a fastening will be completed at every movement of the inserting mechanism inthe fastening insert-ing direction, and that, there-fore` the average time devoted to the insertion of a single fastening will'be onetliird the actual time required for such insertion.

In'ithe preferred embodiment of the invention the Work is fed between successive fastening insertingr operations by a member which engages a partially inserted fastening, and -a further feature of the invention is'the provision cf--means coperating with the Work feeding means just described which will insure the proper feeding of the Work When compar'atively short fastenings are being inserted. To this end the means for forming the fastening receiving opening in the Work-Which, in the preferred embodiment of the inventiomgcomprises 'an avvl driven into the Work by the inserting mechanism, is maintained-With its end in the fas-. tening receiving opening Whilethe head which carries the inserting mec umism swings with it vand the -awl in the direction to feedthe work. It will be noted, therefore, that the invention coliiprises lin this aspect, first, a work feeding means comprising an awl driven into the work by the inserting mechanism and maintained with its end inthe fastening receiving opening by said mechanism while it swings iii the d-i- Irection to feed the Work, and, secondly` a Work feeding means comprising a member which engages a partially inserted fastening and an awl cooperating With said member to insure the proper feeding of the work.

A further feature of the invention comprises vnovel means for determining the length ofthe fastening to be inserted.' A convenient way in 4the preferred embodiment of the invention to decrease or increase the length of the fastening to be inserted is yto cause the strip of fastening material to move respectively in the same direction as, or in a direction opposed to, that in which the gripping means is moving during its in- It Will be noted that in the illustrated construction the strip of fastening material cannot be moved a great distance in a direction opposed to that in which the grippingl means is moving during its inoperative movement without coming into contact with the Work` and that therefore Asubstantially the longest fastening to be obtained by the just described method of varying thev length of the fastenings will be that measured off by the relative movement of the gripping means to a stationarv lfastening strip maintained in its lowerniost position. Such a fastening, in the illustrated construction, vwill be of' a length determined by the vertical position of the grap- A ping means at the time the strip is gripped.

It is sometimes desirable, however, to have proyision for obtaining a fastening of a length greater than any which could be obtained by the method of varying lengths hereinabove refered to, and therefore the present invention comprises also means for varying the length of a fasteningr in a ditl'ercnt manner. Preferably this last-named means ope ates during the ope `ative movement of the gripping means and in coperatioii therewith. When the length of a fastening is varied with the illustrated construction, by the first-destrihed method of varying fasteningr lengths the variation does not involve pulling the strip through the strip retainer at fthe time the increase or decrease in the length is effected. The method of varying the fastening length last referred to does. however, preferably involve the pulling of the fastening strip through the strip retainer. A' convenient Way of varying the length of the fastening in accordance with the last-described method is to provide means for moving the strip retainer over the fastening strip while the strip is held against movement with the retainer by the gripping means.

Another important feature of this inventioii is the provision of means by which the' vlengths of the fastenings may be so controlled automatically that fastenings of varying length may he inserted preferably in predetermined order as to lengths. The provision of such means is especially dcsirable when machines of this kind are to he used for inserting fastenings in the top lifts of heels for ornainental or wear-resisting purposes. As the material from which such fastenings are made is frequently so costly that it adds considerably to the cost of manufacture of the shoes if all the fastenings inserted in the top lift for either or both of the purposes above specified are made sufficiently long to serve ellectively as means .for securing the top lift better to the heel,

and since a few long fastenings only are needed fortbis purpose provided theyybe distributed properly upon the top lift.` a fastening inserting machine which is provided with meansV for automatically controlling the lengths of successive fastenings in such manner that there may be inserted series of fastenings made up of a combination of fastenings of various lengths, for example, a series made up of successive groups each comprising several short fastenings and a single. long fastening, will effect a considerable saving in the cost of material used in oinai'nenting the top lifts, and, in addition, provide additional and effective means for securing the to) lifts to the heels, the top lifts. being usually simply spanked upon the heads of the heel nails. When the length of the fastening is varied, as above described,v by moving the fastening strip either asAV `Iprovisionis preferably made 'forcausing insertion of fastenings To this end the invention aims 'l I 1n the same direction as the gripping means or in a different direction, according as a shorter or a longer fastening is desired than that obtained with the strip stationary, the automatic control of the len "ths of successive fastenings or groups of astenings may convenientlyl be eii'ected by roviding means which controls automatical.` the direction and amount of movement\'o the fastening strip during the inoperative y.movement -of the gripping means. I

The fastening length controlling means has preferably provision for variation of the order in which it causes fastenings of different lengths to be inserted. Inthe preferred embodiment of the invention va single fastening length controlling mechanism controls the lengths of all the fastenings which may be inserted at a single operati'onof the machine. Although vthe number of different combinations as to lengths of fastenings depends upon the capacity of the machine as' constructed, it may be noted that by changing the speed ratio of certain parts or-by distributing the fastening length cont-rol of the different fastening strips among a plurality of vcontrolling mechanisms, the possibility of variety'in the combinat-io-ns may be reatly increased within certain practical imits. g When the'machine-is to be used for inserting fastenings of various lengths 'in predetermined succession, as when,`for example, a few long fastenings and many shortfastenings are-to be inserted into a top lift andthe function of the long fastenings is to' help to hold the top lift on a heel, it is de' sirable that these fastenings be located where they can performthisholding function tov the best advantage. It is especially, desir-4 .,ble that a long fastening belocated. nearone of, or each of, the breast vcorners of the heel. VIn order thatfastenings of a par-J ticular length may be located where desired, it is preferable therefore that thefasteni'ng length controlling means operate in such manner that the length of the initial fastening to be inserted may be predetermined. rto provide a construction which will notk only cause to be inserted a series of fastenings of various lengths but one which Will also cause the first fastening to be inserted, whenever the insertion of `fastenings begins, to be of a predetermined definite length. g j

When the machine is constructed, as hereinabove described, -to insert a series of' fas` tenings which is made ,uplof' groupscorn;`- prising fastenings of` various lengths 'ar-V ranged in predetermined order yas to lengths,

be inserted whenV the beginsto be a selected member.k of one of" said groups. ir

An especial advantage arising l thethe first fastening to Aemployment of'4 the novel fastening length controlling means just described is that in s'o#called quarter slugging in the usual Way, by stoppingthe insertion of fasteningsA after a row of fastenings has been driven from one corner of the heel breast part Way around the heel, and then again starting it in order to drive a single fastening near the other breast corner, a long fasteningl can be located near each breast corner provided the long fastening.

Preferably thev above described fastening i length controlling means is adjustable so that the insertion of fastenings may start with any'desired length of .fastening Within l l .'15 i fastening inserting mechanism' has been set 'to start the insertion of fastenings with a...

the capacityof the machine as constructed', f When vthe fasteningY length controlling means is so constructed andl arranged that it causes a series of fastenings to Ibe inserted lwhich is made up of groups comprising fas` tenings of various lengths arranged in pre'- determined lorder as to lengt-hs, said means y is preferably made adjustable-in such manner thatthe insertion of fastenings may start With any desired member of a group.

A further important novel feature-of this invention resides in the timing of the movements of the strip and the gripping. means. To predetermine accurately. the lengths of the fastenings, it is practically essential that the point'upon they strip at which the gripping means grips it Ito j ect to denite'predetermination, Without regard to varying insert its end be subthicknesses either in thesame strip or in`a plurality of strips which are to loeoperated upon at the same time.

The gripping means has preferably a constant amount ofgripping movement. Itis,

therefore, -obvious that if a plurality. of

strips. of `unequal thicknesses lie"between the "gri ping'1members,l of. the gripping means, t 'e thickeruor.thickesty strip, lwill be *gripped x'st.V If then therebe -amovement of the gripping means relative tothe strips in th direction ofl theirlengths, irst gripped will be moved relatively to the other or others and the'strip next gripped,

-being the next in thickness, Will be gripped at a pointnearer the inserting endthus makin the fasteningfformed from that strip s orter strip desirable to form oneof thesimultaneously severed fastenings shorter than another, a y method of doing so which dependsu-pon ,the difference in thicknesses of the fastening strips willhar'dly be as `satisfactoryas one vfeatures so subject v .to variation; for example, a method made which is independent of possible -b'y `the `provision of separate .fas-

'the lstrip than the one formed from the 'first' gripped. Although it may" be tening length controlling means of th'eLkind hereinbefor described -foreach strip.

lf'One of'f the attained by proper timing of the movements of the strip and gripping means is the avoidance of the scraping of the sides ofthe strip by the gripping means at the time it is actuated to grip the strip. Another object attained by the proper timing of these elements is the avoidance of t-he difficultyv pointed out above when the machine is operatingr lipon a strip, or strips, of varying thicknesses and the rendering certain that when a plurality of fastenings are to be severed simultaneously, the plurality of strips from which `the fastenings are to be severed shall be gripped simultaneously or, at least, gripped successively without any intervening,r moven'ient of the strips relatively 'to each other.

A timing which will effect the desired results above specitied is one in which the gripping means and strip are relatively stationary, so far as movement longitudinally of the strip concerned, at the time the gripping means is actuated to grip the strip. Such timing may be effected in several ways. A convenient way to effect it where the gripping means comprises gripping members pivoted to move from a position in a line bt-lowtheir pivots into gripping position is to canse the strip to remain stationary and .to cause the gripping ends of the gripping -members to move upward into gripping position relatively to their carrier at substantially the same speed as that at vwhich they would be carried downward by the carrier if itwere not forthis upward movement, thus causing these ends to remain stationary relatively to the strip so far as longitudinal movement is concerned, although they are moving transversely of the strip. The gripping movement of each of the gripping members is preferably equal to that-of the other and each is preferably.

land equal movement of the members is preferably continued so that their cutting edges meet at the center of the strip. l

' The invention comprehends also novel means for rendering the machine operative to perform its work and for rei'idering it inoperative after its work has been completed. Included among the operations which the machine is called upon to perform, in order that as little exertion as possible may be re` quired of the operator, is preferably that of raisingthe work supportl to clamp the work against the. work abutment or foot plate after the operator has placed it over the end of said support in proper position to receive the initial fastening: ln machines of this type which are designed to run at high speeds, it. has been'fonnd ditlicult with ordinary actuating mechanisms to operate the actuating mechanisms quickly enough so that the machine may be rendered operative to insert fastenings and then rendered inoperative after a single fastening only has been inserted. To avoid'the necessity of overcoming the inertia of many parts when the machine is rendered operative to perform its work` the greater part of the mechanism of the machine is preferably arranged to be constantly in motion and only so much of the mechanism is thrown out of operation to permit the removal of the work from the work supportl and the placing of another piece of work in position over the work snpport as is necessary to avoid interference with these last-named two operations. To permit convenient replacement ot' one piece of work by another, the work support iS preferably automatically lowered and the insertion ot' fastenings automati'ally interrupted. and these two operations are for this purpose preferably made interdependent, through the actuating mechanism or otherwise, as to the time of their occurrence. The stopping of the insertion of fastenings and theI ylowering of the work support for the replataunent of the work are vpreferably made interdependent to the extent that the insertion of fastenings must be stopped before the work support. is lowered, and that .the work support must he held in its raised position untilthe fastening upon which the inserting mechanism is operating is completely inserted.

In the' preferred embodiment of .the invention hereinbefore referred to, a convenient, 'ay in which the machine may he rendered inoperative to insert fastenings is to cause the fastening strip to move with the gripping mechanism in such manner that there is no fastening measuring 'relative movement of the strip and the gripping mechanism, the gripping mechanism being thus prevented from closing upon the strip to insert and sever a fastening. simple construction for eti'ecting the interruption of the insertion of fastenings in tliemanner 'ust described com )rises means t'or locking' j to pressthe work again against the to lower the work"feialsewvork feeding op-l it is desirable that means be provided forv so connecting the work support and the constantly moving part of the work support operating mechanism .that the connection between these parts may be temporarily, and preferably automatically, interrupted. As hereinbefore ointed out, means is also preferably provi ed for automatically raising the work support into operative position after it has been lowered for the removal or the reception of the work. In the preferred embodiment of the invention, the means for automatically'raising the work support is arranged to be actuated by means set 1n operation by the opepator and is preferably also arranged to effect automatically an operative connection between the work support and the constantly moving partof the worksupport bperating mechanism.

It will be apparent from a study of the mechanisms hereinbefore referred to that,

'toperform their functions properly, these mechanisms must be rendered functionally operative in a predetermined order. Like,- wise in order to perform completely their functions, they must be thrown out of operation in a differentpredetermined order. Means is therefore preferably provided which, after being set in operation by the operator, automatically renders operative, at the proper time, each of the mechanisms which have been thrown out of operation to permit the removal of work .from the machine or the reception of work by it. Preferably the same means is arranged tooperate, also at the will of the operator, to

render inoperative at the proper times each of these mechanisms. In order that both the time and the, energy required for the setting in operation by the operator of the actuating means may be reduced to a minimum, the said means is preferably arranged tol be connected to a constantly moving part of 'the machine, and meansis provided by which such connection maybe easily andA quickly effected. In\the preferred embodiment of the invention, when it is desired to insert several fastenings successively, means is. provided also for disconnecting automatically the actuating means from the constant-l`y\ moving part after the actuating means has received a movement'suflcient to-render operatlve all of the mechanisms which it controls. lThis last-named means,L

as well as the initial connecting means, is arranged to be controlled by the operator, so that the connectionbetween the actuating means and the constantly moving part may be restored at the will of the operator and the actuating means may thus be moved to render inoperative, in the proper order, the mechanisms which it has previously rendered operative.

Vhen a machine which inserts a fastn-- ing for every rotation of the main shaft is designed to operate at high speed, as in the case of the preferred embodiment of this invention, in order that the operator may control the insertionl of fastenings tothe extent that he may, if he desires, through his control of the actuating mechanism, cause the machine to insert a -single fastening only, it is usuallyl essential that more time be given him to make the two movements necessary to control the starting and stopping movements of the actuating mechanism than is consumed by one or even two rotations of the main shaft. "'lt. is therefore essential that a fastening be not inserted upon the first rotation of the main shaft after the actuating means has been set in operation by theoperator, since a second fastening would be inserted' before the operator could control the actuating means to at speeds about 800 rotations -per minute Furthermore, as hereinbefore suggested, in

thepreferred embodiment of the invention the fastening inserting mechanism is constantly in operation and the means for formmg a fastening recelvmg openmg 1n the work/isla operated through said insertingmeclianism. Although it is not essential in the preferred embodiment of the invention that a fastening', receiving opening be 115 formed in the *Work to receive the initial fastening, it is, however, preferable and therefore a fastening is preferably not inserted on the first movement of the fastening inserting mechanism in the fastening inserting direction after the 'actuating means has been set in operation, since one of the movements of the fastening linserting mechanism in the inserting direction after the actuating means is set in' operation is preferably used to cause a fasteningreceiving opening to be formed in the work by the means for this purpose. nIn order that the control of the actuating mechanism may be certain up to themaximum of practical speeds of opfastening 100 stop the 'nsertion of further fastenings, and f eration of such machines, the beginning of the insertion ol the first fastening is ref erably postponed to the third or fourt orl even more remote rotation of the main shaftafter the actuating mechanism has been set in operation. The earlier rotations of the main shaft are preferably used in rendering the various mechanisms functionally opera-tive at the proper times, the actuating means moving in timed relation to the main shaft, so that all parts may be in readiness for the insertion of the tirst fastening when the proper number of rotations of the main shaft has been made.

Preferably a single means is provided for set-ting in operation the actuating means, said first-named means being arranged to be moved in one direction by the opeiator and 'being automatically returned when released, the movement in one direction placing said first-named means in position to control the 'actuating movement of the actuating means and the movement in the other direction placing said first-named means in position to control thatl movement of said actuating means which effects the throwing out of operation of the mechanisms controlled by it. By arranging means of the kiml just described for setting in operation the actuating means, in suitable position, the actuating means mayconveiiiently be controlled by the foot of the operator. such means for setting in operation automatic actuating means having the advantage over the ordinary provision for actuating machines of this type that it requires merely a touch of the operators foot to cause the work support to be raised automatically into ope'ativo position and the inserting mechanism to be rendered operative to insert fastcnings.

Another novel feature of the inventiiin which is'of general utility in machines for inserting fastenings and which is probably a requisite of a fastening inserting machine which is to run at high speed, is the provision of means for automatically stopping the insertion of fastenings at a predetermined point. upon the work. Suc-h means is especially useful in the machine constituting the preferred embodiment ot' the invention.

As hereinbefore suggested. one of the principal. objects of driving fastenings or slugs 'ito the top lift of a heel is oriiainentation of the heel. and the fastenings are therefore usuallvdiiven in such a manner that they form a design upon the top lift. lf a design be made up of many fastenings, it is much more important, in so far as the appearanceis concerned. that it be correspondingly .spaced from the breast ends of the two heels of a pair than that it contain the same number of fastenings upon each ot' the two heels. In the preferred embodiment of the invention, therefore, means -is provided for causing the insertion of fasteiiings to be stopped at a predetermineddistance from the edge of a heel at or adjacent. to one of the corners of the heel,`

preferably at a predetermined distance from one of the breast ends of the heel, and said means is preferably ar'anged to be controlled by the heel in accordance with its contour. Preferably, this means comprises a fceler arranged to be broiightinto contact with the edge of the heel being operated upon, and soconnected with the start-ing and stopping mechanism. that as it drops over a corner of the heel when the row of inserted fastenings approaches said corner it will serve to stop the insertion of fastenings. In order that the end of a row of fastenings may bc gaged from the edge adjacent to another corner of the heel than that which first approaches the insertingV mechanism, in other words in order that it may be gaged from another corner of the heel than the first rounded corner, or either rounded corner, the movement of the feeler necessary to cause the starting and stopping mechanism to stop the insertion of fastenings is preferably made great enough so that the movement permitted to this feeler as it reaches one of the rounded corners is not sutiicient to cause such stopping.

When the machine is being o erated to insert fastenings in a. design w ich'` does not approach the stopping corner of the heel with a continuons row 'of fastenings, for example, when it is being operated to do what is known as quarter slugging inV which a row of fastenings is inserted part way around the heel and then usually asingle fastening inserted into'the heel adjacent to the outer breast corner, that is the breast corner remote from the machine when the insertion of fastenings begins, itis desirable that this single fastening be accurately spaced from the' breast corner adjacent to which it isinserted, and another feature of the invention therefore is the provision of means for affording a two-dimensional positioning of the-work for the insertion of the last fastening. ln the preferred embodimentof this invention. 'this means is prcferablv constituted by the feeler hereinabove described, which at this time does not need to perform its function of determining the location ofthe last fastening of a row of fastenings, In the preferred embodiment of the invention, therefore. the feeler is preferably so constructed and arranged that it. may be thrown out of connection with the starting and stopping mechanism and yet be permittedto slip into position to constitute an end gage for the work during the insertion of the last fastening of a quarter slugging design. lt isffof course, equally as important. so far as ap` pearance is concerned, that the first fasten ing of a design bei-'properly spaced from the breast corner adjacent to which the design starts andtherefore in the-preferredembodiment of the invention means is pro-` vided for aifording a ytwoidimensional positionin'g of the work for the insertion of said lirst fastening. Inasmuch as the fastenings which form the design are successively inserted, and thetworkvis therefore fed between successive* inserting operations, 1t will be seen that'itwill be necessary, after the work has been properlyv located to receive theA first fastening of the design, to remove that portion of the positioning means which constitutes the end gage out of the way 'of the work in order that the work may be f'd past the inserting mechanism. d."

@An import-ant feature of the invent-ion therefore consists in the provision of means for affording a two-di'rnensional positioning of `the work to determine the location upon it of the irst fastening to be inserted, which` is so constructed and arranged that that por# tion of the means which lies within the path of the .work feed-ishall .be automatically withdrawn from said'path before the work is fed. v, i

The invention. includes. also further ittiprovem'ents in theniea'ns for 'feeding th -work. In the v'preferred `embodiment of the invention, as 4h ereinbefore suggested, the work is fedbetween successive inserting operations by the engagement of a laterally movable device with the projecting lpprtion of a partially inserted fastening. The"faitrip.`/L

of fastening material is preferably passed through an opening in this device so that the device servesl not only to feed the work f by engagementwith the partially inserted fastening, but itv also serves to guide thel partial insertion of the next fastening. The

I invention comprehends lmounting the feeding and guiding device above mentioned in such manner that it is preferably yieldingly pressed upon the work at all times except when it is raised, preferably positively, by the carrier at the end of the feeding movement to release it fromI engagement with the projecting end of the partially inserted fastening and except also during the last part lof the fastening inserting operation when it is presthd down Apositively upon the work to mspre ,thel complete insertion of the pre-f viuslp pairtially inserted fastening., Inasmuch as in the preferred construction the fastening-is severed flushl with the upper surface of the feeding and guiding device, it might happen that the free end of a fastening strip would engage the upper surface of the feeding andguiding deviceas it is raised from the work, instead; of passing ,through the guide opening in the same. If

.. this should happen, it might cause breakage of parts of the machineA at the time the strip 'is forced downward by the gripping and sivering means. To ,avoid this possibility,

a novel mounting'of the feeding and gu1dy ing deviceis provided whereby the said device is permitted'to yield in a downward directionas well as in the direction of lts releasing movement.
